Question 1

You are first on the scene of a two-car motor vehicle collision. In one car there are two patients entrapped in the vehicle, while in the other, there is a male driver complaining of chest pain. At this time, your primary concern is:

Accepted Answer

Ensuring personal safety should always be the first concern in any emergency situation. As the first responder, you must make sure the area is safe for yourself and others before attempting any rescue or patient assessment. This includes assessing for any hazards such as traffic, fire, or hazardous material that could pose a risk to your well-being. Once you have confirmed the area is safe, you can then proceed with calling for additional help, triaging the patients, and determining the severity of injuries.

Question 2

Which of the following injuries is most serious, warranting immediate and rapid transport to the hospital?

Accepted Answer

Instability and crepitus to the left lateral chest wall suggest a flail chest, a condition that can severely impair breathing and circulation, requiring immediate medical intervention.

Question 3

During an in-service focusing on care of the trauma patient, the medical director asks if anyone can correctly describe the "platinum 10 minutes." Which of the following indicates the best response?

Accepted Answer

The "platinum 10 minutes" refers to the time frame in which EMS should initiate transport of the critically injured trauma patient to the hospital within 10 minutes of arriving on scene. This is a crucial time frame, as rapid transport to a trauma center can significantly improve the patient's chances of survival and better outcomes.

Question 4

A patient has been stabbed with a knife at the fifth intercostal space on the right side of the chest. Assessment reveals him to be short of breath and coughing. Which of the following questions is it most important for the EMT to ask regarding the weapon?

Accepted Answer

The length of the knife is crucial to determine the potential depth of penetration and the internal structures that may have been damaged, such as lungs or major blood vessels.

Question 5

Which of the following statements concerning trauma is true?

Accepted Answer

Patients with multisystem trauma may have injuries to multiple organs or systems, which can complicate treatment and increase the risk of mortality compared to patients with single-system injuries. Falls are a common cause of trauma, but not necessarily the leading cause. Mechanism of injury is one factor that can help predict patient outcome, but it is not always the best predictor. A "spider web" or "star" pattern on the windshield may indicate an impact with an object or other form of trauma, but it does not necessarily mean the patient impacted the windshield with their head.

Question 6

You are assessing a male patient who was stabbed three times in the chest and abdomen. As you begin your primary assessment, you note him to have a decreased level of consciousness and gurgling respirations. Your next action would be to:

Accepted Answer

The presence of gurgling respirations suggests an obstructed airway, which can be life-threatening. The immediate action should be to suction the airway to clear any obstacles and facilitate breathing. Checking the pulse can wait until the airway is clear, and obtaining an SpO₂ reading or applying a cervical collar would not address the primary concern of airway obstruction.

Question 7

A 23-year-old roofer has fallen 20 feet from the roof of a house into shrubs below. Aside from superficial abrasions and complaint of soreness, you detect no obvious injuries. Consequently, the patient states that as long as his legs are not broken, he does not see the need to go to the hospital. As a knowledgeable EMT, your best response would be:

Accepted Answer

It is important to educate the patient that even if they feel okay, there could be underlying injuries they are not aware of, especially from a fall of this height. The patient needs to be evaluated in the hospital to rule out any potential internal injuries that could be life-threatening.

Question 8

Which of the following describes the "platinum 10 minutes" as it applies to care of the trauma patient?

Accepted Answer

The "platinum 10 minutes" refers to the target scene time for EMS when responding to a seriously injured trauma patient. This includes the time it takes for EMS to arrive at the scene, initiate care, and transport the patient to a medical facility within 10 minutes. This quick response time is critical for improving the patient's chances of survival and reducing long-term complications from their injuries.

Question 9

You arrive on the scene of a motorcycle accident and find an unresponsive male patient lying in the middle of the road with blood coming from his ears and nose. He was not wearing a helmet and has snoring respirations. Which of the following would be most appropriate in the care of this patient?

Accepted Answer

The patient is unresponsive with snoring respirations, indicating the need for immediate airway management. Primary assessment, airway management, and oxygen administration should be done as quickly as possible, followed by immobilization and transport to the hospital within 10 minutes of arriving on the scene. Time is critical in this case, and delaying transport may adversely affect patient outcomes.

Question 10

The EMT understands the importance of evaluating the mechanism of injury when he states:

Accepted Answer

Evaluating the mechanism of injury can give the EMT insight into the potential injuries the patient may have sustained and can guide their assessment and treatment plan. It can also indicate the need for emergency transport to the hospital. However, it cannot determine the patient's outcome.

Question 11

After assessing the following patients, which would the EMT identify as suffering from multisystem trauma?

Accepted Answer

The patient in option B has injuries in multiple body systems: head (laceration), musculoskeletal (open fracture), and potentially neurologic (dizziness). This indicates multisystem trauma. The other patients have injuries limited to one body system, such as the shoulder, leg, or head.

Question 12

A patient, who was constructing a bomb in his basement, has sustained a secondary phase blast injury. Which of the following presentations would the EMT most likely observe?

Accepted Answer

Secondary phase blast injuries are caused by flying debris and bomb fragments, which can lead to penetrating trauma such as a screwdriver impaled in the arm.

Question 13

You are assessing a patient involved in a motorcycle accident. He states that he saw an oncoming car and "laid the bike down" to avoid an outright collision. He was wearing a helmet. Which of the following injuries would make sense given the action of the motorcyclist?

Accepted Answer

The answer of You are assessing a patient involved in...

Question 14

A bullet fired from a gun at close range passes through the patient's liver. However, on autopsy, the coroner discovers that the man's pancreas, stomach, and gallbladder were also injured, even though not in direct contact with the bullet. As a knowledgeable EMT, you would recognize that which of the following is responsible for injury to these additional organs?

Accepted Answer

Cavitation refers to the creation of a temporary cavity within the tissues as the bullet passes through. This cavity can cause secondary injuries to nearby structures even if they are not directly hit by the bullet. Therefore, cavitation is responsible for the injury to the additional organs in this scenario. Drag force is the resistance encountered by the bullet as it moves through the air or tissue, and profile impact refers to the specific angle at which the bullet strikes the target. Blunt injury results from direct physical trauma without penetration, which is not the case here.

Question 15

An 8-year-old boy fell forward off of a swing onto outstretched arms. He did not hit his head or lose consciousness and is complaining of left forearm pain. There is deformity to the left wrist, but no other injuries or life threats. His vital signs are pulse 132, respirations 20, blood pressure 108/62, and SpO₂ 100%. The proper care of this patient would be:

Accepted Answer

The correct care for this patient involves splinting the forearm to immobilize the injury and applying a cold pack to reduce swelling and pain before transporting the patient non-emergently. This approach addresses the immediate need to stabilize the injury and manage pain, without the need for advanced life support interventions or emergency transport, as the patient's vital signs are stable and there are no life-threatening injuries.

Question 16

Which of the statements below best characterizes the capabilities of a Level III Trauma Center?

Accepted Answer

A Level III Trauma Center has some surgical capabilities and can provide initial stabilization and treatment for trauma patients, but will generally transfer patients requiring more comprehensive care to higher-level trauma centers.

Question 17

A male patient has sustained gunshot wounds to the neck and abdomen. He is unresponsive and has gurgling respirations. Your immediate action would be to:

Accepted Answer

The patient has gurgling respirations, indicating potential airway obstruction. Suctioning the airway will help to clear any obstruction and maintain a patent airway. However, all other interventions may still be necessary after suctioning.

Question 18

You have arrived on the scene of an explosion in a warehouse used to store fertilizers. A paramedic, who has already triaged the nine patients involved, directs you to a young man sitting under a tree. The man states that he is having excruciating ear pain. The initial assessment and rapid trauma assessment reveal no obvious injuries. Given this presentation, the EMT would recognize which of the following?

Accepted Answer

The young man's symptoms, combined with the fact that he was near the site of an explosion, suggest that he has suffered a primary phase blast injury to the inner ear. This occurs when a sudden increase in pressure from the blast wave causes damage to the delicate structures in the inner ear, resulting in symptoms such as hearing loss, tinnitus, and ear pain. While other types of blast injuries can also cause ear damage, the fact that the patient is experiencing intense ear pain without any visible injuries suggests that the blast wave was the likely cause of his symptoms.

Question 19

Which of the following is a high-velocity wound that carries the greatest risk for death when considering the concept of cavitation?

Accepted Answer

A gunshot wound to the spleen is a high-velocity wound that can cause significant cavitation, leading to severe internal bleeding and a high risk of death due to the spleen's vascular nature and its role in blood filtration.

Question 20

Which of the following best describes the goal of a trauma system?

Accepted Answer

The goal of a trauma system is to get the right patient to the right facility in the right amount of time. This is done through a coordinated system of prehospital care, transport, and hospital care that ensures each patient receives the appropriate level of care based on their individual needs and the severity of their injury. Providing the highest level of care within a certain time frame or providing all patients with a complete battery of tests and specialists are not the primary goals of a trauma system, although they may be important components of the system. Transporting as many patients as possible by air medical transportation is also not the primary goal, but rather a decision made based on the individual patient's needs and the availability of resources.
